The Viecar VC300 code reader supports all OBD II protocols, including the newly-released Controller Area Network (CAN) protocol.
Though it is small, it is able to retrieve same information as large expensive scanners!

A small number of gasoline vehicles (1994 and 1995 model year) are the OBD II compliant. To verify if a 1994 or 1995 vehicle with OBD II compliant or not, check the Vehicle Emissions Control Information (VECI) Label which is located under the hood or by the radiator of most vehicles.
That is, if the vehicle is OBD II compliant, the label will designate "OBD II Certified". Additionally, Government regulations mandate that all OBD II compliant vehicles must have a "common" sixteen-pin Data Link Connector (DLC).

For your vehicle to be OBD II compliant it must have a 16-pin DLC (Data Link Connector) under the dash and the Vehicle Emission
Control Information Label must state that the vehicle is OBD II compliant.
